HMCS Iroquois – RAS Excercise?

A reader sent me the above photo of HMCS Iroquois departing the harbor at a very high rate of speed this morning. (Just look at the wake) I have no idea what was up, how ever she appeared to be circling in the outer anchorages.

She returned to the dockyard, Around 1300, following behind HMCS Preserver. She had her main gun pointed to Starboard, and the forward RAS (Replenishment at Sea) King Post erected on the bow.
